Best budget head for boosted 408?
I know everyone runs the 317 castings but I am in the process of trying to get everything together so I can start building my engine. I am new to forced induction so I don't know much but I have been thinking about either going with the 317 heads, ls6 heads, or maybe even the l92 heads. The motor is going to be 9.5.1cr with a f1a blower running somewhere in teh 14 to 16lbs of boost range and hoping for 750 to 850 power. I know a thicker deck is my friend with boost but I don't want to spend 2500k plus on heads right now. Thanks for any help and tips you guys might have.

Since you were asking for a good inexpensive head, take a look at the Patriot LQ9 Stage 3 heads. $1,285.00 and they do the job quite nicely for what you pay for. Check out this build where we reused the Patriot Stage 2 heads from the customer's old 346 on his new LS2/402. http://www.exoticperformanceplus.com...Car.php?car=40 Bob

I posted the same reply in another thread:
If you search on Ebay you'll find a guy who sells bare All Pro castings for $700 including guides. They're as cast, but you can have them finished for $150 to have the guides installed and $180-200 for a good valve job. You'll need springs and valves, but you can get valves for $240 and springs for $250. You'll have a 230cc after market casting with a thick deck, solid rocker pad, 1/2 inch pushrod holes, etc... for $1600. That's about the same as you'd be able to get a set of stock ported castings for.

Out the Box ARP Head studs.
I could run all day at 20 psi and nothing.... on good fuel of course.
When we went beyound that i would start to push water.
At 22+ i would start to push a lil water even on the dyno.
The 1132rwhp pull we had dripping from the back of the heads some...
Shawn @ VA Speed is doing a few things to the new heads and motor.
Ill be sure to post up when its done.

Out of the box L92 heads. We saw 24psi for a split second this past weekend (22 most of the run). Its got the L19 ARP studs on it. It went nearly 130mph in the 1/8th. Once I get more timing put in it at the bottom it'll go alot quicker (and faster too). Not even 1 single drop of water in the overflow.
